Hello, In the column application, while the axis system is prepared at 1/50 scale, the columns are prepared at 1/20 scale by enlarging 2.5 times. Large columns can coincide with the other column according to their growth direction. First, check the growth limits of the columns. Some designers can take the columns according to 2 floors, 1/25 scale. You can change the scale of the columns in the settings that appear before the column is applied. Alternatively, you can select the column and leave the "Always detail outside in the application" option checked in the column settings. The big column on the left according to the picture you added... After this process, when you get a colon application, that column is drawn at 1/50 scale, without giving any details, and its detail is drawn as 1/20 on the outside. Since the column will not be enlarged, it does not overlap the other column.
